WebbAnswer: Explanation: Because smaller ions are more hydrated due to their more intense electric field they tend to have larger hydrated radii than larger ions. Which is most strongly hydrated Li+ Na+ K+ Rb+? Li+ ions are more readily hydrated than k+ ions. This is because lithium ions are usually smaller than potassium ions.

We assume that the … city dentists wellington googleIons may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller. Similarly, when an electron is added to an atom, forming an anion, the added electron increases the size of the electron cloud by interelectronic repul… dictionary spanish to german
